Tesla, BMW and Nissan meeting in secret to discuss charging tech

It's interesting what's happening in the electric vehicle field. It used to be that BMW and Tesla were competitors. Then – and of course they're still competing, especially in the public mind – they were working together on ... something. Maybe. And now, the Financial Times reports that the two luxury automakers are meeting with Nissan. Again, maybe. The scuttlebutt is that the three companies are interested in working together on something to do with charging electric vehicles, potentially a global recharging standard. Currently, when it comes to fast charging, BMW uses the SAE Combo standard, Nissan uses CHAdeMO and Tesla uses its own Superchargers. The meeting was prompted by Tesla opening of all of its patents the other day, FT says. Speaking during the recent annual shareholder meeting, Musk said he was "more than happy to have other manufacturers" use Tesla's Superchargers but that, "there is no other electric car that can accept anything close to 135 kilowatts." Let's assume the technical hurdle can be overcome. With any potential patent/licensing problems out of the way, these discussions with BMW and Nissan might be revolving around this other angle that Musk mentioned: "They (other automakers) just have to contribute to the capital cost, so figure out what percentage of the time are their cars using the Supercharger network and then they can make a contribution proportionate to their customer usage of the Supercharger network." That certainly sounds like something that could take some time to figure out.

BMW M4 Convertible poised for Goodwood unveil

It shouldn't be a shock that BMW is working on a convertible version of the M4. Not only have we caught it testing twice, but this is an automaker that seems willing to build a vehicle for nearly every buyer's needs. Evo claims that the high-performance droptop is going to debut at this year's Goodwood Festival of Speed in England from June 26-29.
Judging from the spy shots we've seen, the M4 Convertible will consist of a retractable hard top like the 4 Series cabrio. Other than the roof, there aren't expected to be many changes from the coupe. The engine will be the same turbocharged, 3.0-liter inline six-cylinder engine, but the added weight of the roof and its mechanism may take a small bite out of performance.
We spoke to BMW USA about the rumor and were told that it has no comment at this time. After the M4 Convertible, Evo claims that BMW is working on a M4 Gran Coupe. How that would be all that different from an M3, isn't exactly clear.

2015 BMW X4

BMW has been in the line-blurring business of late, with the original X5 "Sports Activity Vehicle" muddling the line between SUVs and sport sedans in 1999, the 5 Series Gran Turismo challenging what our definition of "Gran Turismo" means in 2009, and pretty, low-roofed four-doors like the 6 Series Gran Coupe and the fresh new 4 Series Gran Coupe broadening the meaning of the word "coupe."
In the midst of all of this, BMW blurred the lines around both the SUV and coupe genres with its big, heavy, and in many ways ridiculous X5-based "Sports Activity Coupe" (cue collective eye-roll), dubbed X6. Auto wags scoffed at its lack of utility, compromised outward visibility and added cost, but a more emotional public was apparently smitten enough by its aggressive looks to avail itself of some 250,000 of them worldwide in six model years on sale.
Enter the all-new 2015 X4 crossover - err, "Sports Activity Coupe" - which BMW hopes will perform as well in the compact category as the X6 has on the next rung up the ladder. Like the X6, the X4 is a tough sell on paper: it's more expensive and less practical than the X3 on which it's based; it's heavier, despite the loss of interior space; and it doesn't even hold as much stuff in the back as the 3 Series wagon. As with the X6, the X4 is essentially a high-riding style statement that, like proper coupes (the two-door kind), says to the world, "You fools can take your need for practicality and shove it. I just want to look good."
